    Unhappy Brown leaves Paph sanderianum, HELP!

    I got this sanderianum orchid and have no idea how to take care of it. Orchid and I desperately need help. I do not know if I should use bark or moss, how often water it and where should be a good spot for it. All leaves on it are going brown. Can I still save it?? Please help us. Thank you! It should be like on the pic on the left and it is ... poor thing on the right

    Im not familiar with orchid rot issues much but that looks like erwinia...or sunburn. . Looks like you have it in moss i would repot in bark and keep alitte drier after cutting off the rot and repotting. cant tell but it dosent look like the crown is damaged and is mostly on the leaf so it may be sunburn. Hopefully someone else will chime in here.

    First off, I am not an expert on Paphs and I know others with more experience will chime in. Does the outer pot drain? Is it always in the outer pot? What kind of conditions have you been growing it in? The brown leaves could be rot, sunburn or possibly even cold damage. I suspect rot. If it is really wet inside its pot, it needs to be taken out of its current pot immediately and let to dry out while you decide how to re-pot it. When you have it out of the pot, you can check the roots to see if they are healthy. The leaf that is on the bottom right in the photo should be cut off with sterilized scissors or shears, then sterilize them between cuts and remove the damaged part of the leaf above it. Keep an eye on the other, smaller damaged areas to see if it is spreading, if so, trim them back to healthy tissue too. Usually when you trim an orchids leaves that way, the remaining part of the leaf will continue to live and produce food for the plant. You can dust the cuts with cinnamon, but keep it off the roots. It will act as an anti-fungal on the leaves, but damage the roots. Also check to be sure the crown isn't planted under the media.

    If the plant has been in full sun and isn't too wet, then it may be sunburn. I'd still remove the most damaged leaf and part of the next most damaged one.

    More pictures from different angles might be helpful, also does the inner pot slide out of the outer one? If so you can take it out, then photograph it, we might be able to see more clearly.

    Others can help you figure out the best media for it. I only have one Paph and its variagated - I was told it needs a little different care than the ones like yours. I wish you luck, that's a really cool Paph!

    I did have it for a pretty long time on the top of the shelf in the kitchen. Probably it was a bad idea but there was no other option then (I moved recently). I do not know how to water it. I kept it pretty dry for some time and other times gave more water but honestly, from the moment I got it it was in pretty bad shape, with those brown spots and two leaves died a very long time ago. I will buy a bark tomorrow and put cinnamon on the trimmed leaves. Thank you for the tips!!

    I speculate that you're suffocating the roots, and may have fostered the beginning of a fungal infection.

    All orchids need moisture coupled with good airflow to the root system. The combination of the pot, the medium, and your preferred watering regimen should provide that.

    I agree with Carol that it would pay to unpot it, let it dry out completely (1 day should do), then repot it better. Keep it in bright, indirect light only.

    I have several Paphs, species and similar to yours: PaphMadMan provided me with great advise on how to care for them when I first introduced them into my collection. First, not all Phaps are cared for the same. The sanderianum and rothschildianum type love filtered sun, mine get almost as much sun as the cattleyas. Remember, Phaps are terrestrial. The potting mix is similiar to the that used with Phals (fir bark and spagnum moss), but I added a bit more moss and water twice a week so that they always moist but not soggy or in standing water. They do not like their roots to touch water or they will rot. As the plant grows it will definitely become a space-hog but the blooms are well worth it.

    From the pic you provided: first I would take it out of that ceramic pot, repot it in a plastic orchid pot for air flow. It looks like you may have a fungal infection. Trim the leaves with a sterile cutting tool as the leaves die. I am fighting rust-fungus and it is an ongoing battle.

    Thank you all very much for all advices! Today I will do as best I can to try to save it and hopefully I will succeed.
    Yesterday I watered it so now I will take it out of the pot, let it dry and repot tomorrow morning into the new bark.
    I already trimmed the lives.
    Bechinolina - I really do not know the proper names for orchids but on the mark it says Paph Michael Koopowitz.
    THANK YOU!

    Paph Michael Koopowitz is a primary hybrid of sanderianum x philippinense ...
    Let us know how the roots look when you remove the medium.

    Michael Koopowitz is an hybrid between Paph philippinensis and Paph sanderianum. The picture you used is not sanderianum and i'm doubtfull about being M.K.
    It could be Paph Chiu Hua Dancer (gigantifolium*sanderianum) or gigantifolium*MK. but i'm not an authorised expert! i think i knew the picture you used, but can't remember from were...
